Whether you're outlining your next novel, or just jotting down a to-do list, the Edgar Allan Poe Signature Notebook is exactly what you need. Filled with dozens of quotes and little-seen photographs from both his public and private life, this notebook lets you draw inspiration from one of the country's most imaginative storytellers as you put your own thoughts on paper.

Henry Eliot leads us on a twisting journey through the world of mazes, real and imagined, unraveling our ancient, abiding relationship with them and exploring why they continue to fascinate us, from Kafka to Kubrick to the myth of the Minotaur and a quest to solve the disappearance of the legendary Maze King.
